Field Guard 1.0.1 Declares the PHP floor in composer.json: >=8.1. Checked rather than assumed. PHPCompatibility reports the codebase clean from 8.1 upward, Drupal 10.6 requires >=8.1.0, and this module takes no runtime dependency beyond core. The drupalcode previous-major lane already runs this suite on PHP 8.1.34 and passes. No resolution outcome changes today; the declared core range already implies the same floor.
